What is a linear pair of angles?

Back

A linear pair of angles is a pair of adjacent angles formed when two lines intersect. The angles are supplementary, meaning their measures add up to 180 degrees.

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more other lines in a plane.
